oAsfr vaincre-WHEEL. 7

To .Z whom it may concern: Y

Be it known that l, WALTER S. ALLEN, a

citizen of the V'United ltates of America', re-

siding at Detroit, .in the county of Vayne Awheels, being particularly designed fory use on motor trucks and similar vehicles, and it is the object of the invention to obtain a simple construction which maybe cast with the use of comparatively few baked sand cores and'whichis free from objectionable strains incident to the cooling and contraction ofthe metal. To this end the invention consists in the construction as hereinafter set forth.

' In the drawings:

Figure 1 is a section through the wheel in the plane of the axis thereof;

Fig. 2 is a side elevation, partly in section;

Fig. 3 is a cross-section through the spokes on line 3 3' of Fig. l.

A is a hub which is of a simple barrel form, being rovided withinternal shoulders- Br and for receiving the end thrust from the bearings. It may also be provided with a vflange D at one end for attachment to` the driving shaft'. E isa hollow rim having a continuous inner wall F and flaring outwardly from )opposite sides of the central plane of the wheel. The outer peripheral wall of the rim is formed from flanges G and Gr which project inwardly from the side wallsvH thereof, leaving an o en af) intervals by cross braces I, which as shown are of'T-shaped section. J are spokes extending radially from the hub to the rim and of a solidv cross-sectionwhich tapersfrom the central plane of the lwheel toward the opposite sides. At the point of intersection of the outer ends of the spokes with the inner wall of the rim vthe central portion is cut away, as indicated at K, so as to reduce the mass-of metal. This is an important feature, for any concentrated mass of metal will lbe slower in cooling than other portions and will result in setting up strains in the finished wheel. On the other hand,

one of channel therebetween which is bridgedAV A specification of Letteifsratent. patented Sept, 12g, 1920. ["fAgpiication inea April as; ieial; "segiairNt-)aeaieaf f l o f To strengthen the connection between the Y vspokes and the rim, brace ilanges 'La may be arranged upon opposite 'sides of the spoke, extending ldiagonallyv in the central plane of the wheel from the spoke to the i. rim- These brace flanges are alsor preferably cut away at theangle of intersection between the spoke and rim, as indicated at M, this also being for the purpose of avoiding a g concentrated mass of metal.

A wheel of the constructiony described may be -easily cast, as the tapering form of the spokes, as well as the flaring form of the` inner wall oftheprim will provide abundant' draft and will enable the casting of 'the wheel largely with v green "sand molds. The

structure is also one `whichin cooling will',` i

not 1 set up `objectionable strains, which would diminish the strength of the wheel.'

What I claim as my invention'is l. A c astY vehicler wheel, comprising vav hollow rim, a hub, radial spokes of solid section comparatively narrow in the plane of the wheel, wide in theplane of vthe axisV and'tapering from the central plane to they opposite sides extending between and formed integral with said Vhub and rim, a

portion of the metal at the point of inter-f` section at one end of the spoke being cut f,-

away to reduce the inassand avoid strains.

2. A cast vehicle wheel, comprising va hub, a hollow rim and a series of .spokesextending between said. hub and rim and integral therewith, said spokes being'of a cross-sectapering from the central plane' to the opmetal and avoid strains; Y.

3. -A cast vehicle wheel, comprising a hub, a hollow rim and spokes extending radially vtion comparatively narrow in theplane of i the wheel, wide in the plane of the axis, and o 10o l' l between said hub andv rim and integral Y therewith, said spokes being of a solid crosssection comparatively narrow in the plane ofthe wheel, wide in the plane of the axis, being'also of'a tapering form from'the cenbrace web extending diagonally from the tral plane towardthe opposite sides, and a i the metal at the center of the spoke and brace adjacent to the rim being cut away to reduce the mass and avoid strains.

4L. A cast vehicle wheel, comprising a hub, a hollow riin and a series of radial spokes extending between said hub and rim and integral therewith, said rim having its inner wall Haring outwardly from the central plane of the wheel toward the opposite sides 10 thereof, said spokes being of a solid crosssection comparatively narrow in the plane ol the wheel and wide in the plane of the andftapering from the central plane toward the opposite sides, and diagonal brace webs extending from the spoke to the rim, the metal at thel center of the spoke and brace adjacent to said riln being cut away to reduce the mass and avoid strains.

ln testimony whereof I aiiX my signature.
